Abstract:
A one-step catalytic synthesis of 6-substituted 4-phenyl-2-(2'-pyridyl)quinolines provides electronically differentiated ligands without solvent, inert atmosphere, metal contamination, or chromatography. Gold(III) complexes formed from these bidentate PyQuin ligands were characterized and studied by single-crystal X-ray diffraction. The cationic gold(III) chloride synthesized from 6-methoxy-4-phenyl-2-(2'-pyridyl)quinoline has a distorted square-planar ligand environment. Diamagnetic neutral gold(III) complexes from methoxy-, methyl-, and phenyl-PyQuin ligands exhibit a long axial Au-N2 interaction.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
